Becky and I pay NZ22.3 cents per kilowatt hour for electricity, so reading about this “fridge” was nearly a religious experience for me.
After we get our desperately needed solar hot water system, this will be the next project:
Using vertical doors in refrigeration devices is an act against the Nature of Cold Air. Understanding and cooperating with Nature rather than acting against it leads to much better efficiency.
My chest fridge (Vestfrost freezer turned into a fridge) consumes about 0.1 kWh a day. It works only about 2 minutes per hour. At all other times it is perfectly quiet and consumes no power whatsoever. My wind/solar system batteries and power-sensing inverter simply love it.
